Abstract :
Wounds are of a variety of types and each category has its own distinctive healing requirements. This realization has spurred
the development of a myriad of wound dressings, each with specific characteristics. It is unrealistic to expect a singular
dressing to embrace all characteristics that would fulfill generic needs for wound healing. However, each dressing may
approach the ideal requirements by deviating from the ‘one size fits all approach’, if it conforms strictly to the specifications
of the wound and the patient. Indeed, a functional wound dressing should achieve healing of the wound with minimal time
and cost expenditures. This article offers an insight into several different types of polymeric materials clinically used in
wound dressings and the events taking place at cellular level, which aid the process of healing, while the biomaterial dressing
interacts with the body tissue. Hence, the significance of using synthetic polymer films, foam dressings, hydrocolloids,
alginate dressings, and hydrogels has been reviewed, and the properties of these materials that conform to wound-healing
requirements have been explored. A special section on bioactive dressings and bioengineered skin substitutes that play an
active part in healing process has been re-examined in this work.
